Verdict
4.83 g per servingone dose · studies use 10–12 g of essential amino acids
Below research doseOne serving contains 4.83 g; studies use 10–12 g in one dose.
One serving gives 4.83 g, so reaching the low end of what studies use (10 g) takes 2.1 servings at once; it ranks 14th of 20 EAA supplements here by dose.
To reach the research dose. It would take 3 servings at once (3 scoops), 14.49 g, to reach the 10 g studies use.
Amino acids, one by one
All nine essential amino acids are on the label. 0 of 9 reach what a 10 g dose shaped like the WHO adult requirement pattern holds. The lowest is tryptophan: 3.5 mg, 2% of 217 mg.
| Amino acid | In one serving | In 10 g at the WHO pattern | Share |
|---|---|---|---|
| Leucine | 2 g | 2.12 g | Below · 94% |
| Isoleucine | 550 mg | 1.09 g | Below · 51% |
| Valine | 500 mg | 1.41 g | Below · 35% |
| Lysine | 680 mg | 1.63 g | Below · 42% |
| Threonine | 475 mg | 815 mg | Below · 58% |
| PhenylalanineWHO figure: phenylalanine + tyrosine | 350 mg | 1.36 g | Below · 26% |
| MethionineWHO figure: methionine + cysteine | 200 mg | 815 mg | Below · 25% |
| Histidine | 72 mg | 543 mg | Below · 13% |
| Tryptophan | 3.5 mg | 217 mg | Below · 2% |
How this works: the WHO's adult requirement for each essential amino acid (WHO/FAO/UNU 2007, Table 23), scaled to a 10 g dose, the low end of the 10–12 g of essential amino acids in one dose in the ISSN's 2018 review. No study gave these amino acids one at a time at these amounts: it shows how a serving's mix compares with what the body needs, not a dose of each. The WHO figures for methionine and phenylalanine include cysteine and tyrosine, which the body can make; tyrosine is counted when the label lists it. Salt forms are counted as the amino acid in them (lysine hydrochloride as 80% lysine), and a DL form as half L.
